Problem when I use my own species list

[Jeff37]

Hi,
I'm using a species list that fits the best the regions where I usually record bats. To to that I'm adding the flag --slist put-your-files-here/ where there's is my own species_list.txt. It works well but I noticed that at least one species (Pipistrellus nathusii) never appears anymore in the output. When I run the API with default species list, ie. no --slist flag, the species appears...
Can it be a bug somewhere or am I missing something in the spelling? To be sure I spelled correctly, I copied the english species list where I removed unwanted species.
Any hint?

Here is the content of my species_list.txt :
